At the moment, the edt-ft5x06 driver can control a single regulator
("vcc"). However, some FocalTech touch controllers have an additional
IOVCC pin that should be supplied with the digital I/O voltage.
The I/O voltage might be provided by another regulator that should also
be kept on. Otherwise, the touchscreen can randomly stop functioning if
the regulator is turned off because no other components still require it.
Implement (optional) support for also enabling an "iovcc-supply".
The datasheet specifies a delay of ~ 10us before enabling VDD/VCC
after IOVCC is enabled, so make sure to enable IOVCC first.

This converts the CYTTSP "Cypress TrueTouch Standard Product"
to YAML bindings and fixes and adds some things in the process:
- Rename the bindings file to cypress,cy8ctma340 after the main
product in the series.
- Add proper compatibles for the two known products:
CY8CTMA340 and CY8CTST341.
- Deprecate "cypress,cyttsp-spi" and "cypress,cyttsp-i2c"
because device compatibles should be named after the
hardware and not after which bus they are connected to.
The topology implicitly tells us which bus it is and what
interface to used.
- Add VCPIN and VDD supplies, these are present just like
on the CY8CTMA140.

u64 cast to stop losing bits when converting unsigned long to loff_t
(and let's use shifts throughout, rather than mixed with * and /).
Use round_up() when advancing pos, to stop assuming that pos was already
THP-aligned when advancing it by THP-size. (This use of round_up()
assumes that any THP has THP-aligned index: true at present and true
going forward, but could be recoded to avoid the assumption.)
Use xas_set() when iterating away from a THP, so that xa_index stays in
synch with start, instead of drifting away to return bogus offset.
Check start against end to avoid wrapping 32-bit xa_index to 0 (and to
handle these additional cases, seek_data or not, it's easier to break
the loop than goto: so rearrange exit from the function).
[hughd@google.com: remove unneeded u64 casts, per Matthew]

No problem on 64-bit, or without huge pages, but xfstests generic/308
hung uninterruptibly on 32-bit huge tmpfs.
Since commit 0cc3b0ec23 ("Clarify (and fix) in 4.13 MAX_LFS_FILESIZE
macros"), MAX_LFS_FILESIZE is only a PAGE_SIZE away from wrapping 32-bit
xa_index to 0, so the new find_lock_entries() has to be extra careful
when handling a THP.
